This study aims at testing the theoretical issue according to which multinomial logit (MNL) would give lower performance than a mixed multinomial logit (MMNL) in the presence of heterogeneity. To do so, we construct two samples of patients surveyed within the same regions in rural China, but of...

This paper offers an indirect measure of patient welfare based on whether patients comply with the prescription they receive. Adherence behavior is supposed to reveal patients' subjective valuations of particular therapies. We write a simple theoretical model of patient adherence behavior, that...

The use of cost-benefit analysis (CBA) is increasingly advocated as a tool for supporting water planning decisions, in particular at the local (site) level. This paper questions whether CBA is relevant for evaluating groundwater management options at the scale of large regional aquifers. It...

Few studies have explored, to date, the issue of the monetary valuation of non-fatal injuries caused by road traffic accidents. The present paper arises interest in this question and aims to estimate, by means of the contingent valuation, the willingness to pay (WTP) of French households to...

This paper investigates how the general public behaves when confronted with low probability events and ambiguity in an insurance context. It reports the results of a questionnaire completed by a large representative sample of the French population that aims at separating attitudes toward risk,...

Using a unique cross-section sample from 10 OECD countries, we estimate willingness to pay for better quality of tap water. On the pooled sample, households are only willing to pay 7.5% of the median annual water bill to improve the quality of tap water. The highest relative willingness to pay...

Differentiated prices, bundling, Web auctions : firms' pricing practices are evolving. When there is no market or for customised pricing, the willingness-to-pay concept seems to be interesting. This article aims at presenting a synthesis of the marketing research stream relative to willingness...

Tanzania has created, since the mid-90s, an original institutional framework for water and sanitation management made of a mix of decentralized initiative and public control. This article presents this framework and its functioning on sanitation issues in the town of Moshi, a medium-sized town...

We explore the influence of a neutral cheap talk script in three typical scenarios used in the CV literature devoted to the valuation of air pollution effects. We show that cheap talk has a differentiated effect depending on the scenario implemented. It decreases protest responses with no effect...

Following an invitation to tender of the French Foreign Office on research on management of urban waste-water in developing countries, a consortium of institutions from France and Tanzania has been created in 2000. The proposition of the consortium has been accepted; it included a research project...
